Navigare necesse est. A possible reconstruction of a maritime activities related occupation based on the presence of auditory exostoses in an individual from the Roman period city of Iader

Large bilateral auditory exostoses were recorded in the skeleton of an adult male buried in the Roman period necropolis of Zadar-Relja (the Roman colony of Iader) in southern Croatia. As the occurrence of auditory exostoses in both past and modern populations has been correlated with prolonged exposure to cold water, the authors propose that during his lifetime this individual performed activities requiring frequent contact with cold water for an extended period of time. Apart from auditory exostoses, this individual also exhibits other pathological changes including pronounced skeletal robusticity, benign cortical defects at the insertion of the pectoralis major muscles on both humeri and at the attachment sites of the costoclavicular ligaments on both clavicles, and vertebral osteoarthritis in the cervical and thoracic vertebrae. Based on the geographic and climatic location of Zadar the observed skeletal changes, together with the archaeological context of the site, the recovered material artifacts, written historic sources, and comparisons with similar studies suggest that the most plausible explanation for these changes is that this person spent most of his life working aboard a sea vessel as a sailor, boat builder or a fisherman, whose duties included the frequent an intensive use of oars.
